Method Detail

getEditProcess

public Transition getEditProcess(SingleTableFormSheet stfs,
                                 SaleProcess p,
                                 SalesPoint sp)

Description copied from class: EditButtonStrategy

Get the first transition of the process that will perform the editing. The process can have any number of Gates and Transitions and display any number of Form- and MenuSheets. Normally, the sub-process should end at the gate at which the SingleTableFormSheet is being displayed, which can be obtained by SingleTableFormSheet.getGate().

Specified by:

getEditProcess in class EditButtonStrategy

Parameters:

stfs - the SingleTableFormSheet that triggers the sub-process.

p - the process into which the sub-process will be implanted.

sp - the SalesPoint at which the FormSheet is displayed, if any.

getCheckGate

protected Gate getCheckGate(SingleTableFormSheet stfs)

Get the Gate that checks whether the removal is allowed. If this is the case, the Gate must be left through getRemoveTransition(org.salespointframework.desktop.formsheets.SingleTableFormSheet), otherwise, a transition to the SingleTableFormSheet's gate should be triggered.

Parameters:

stfs - the FormSheet that triggered the operation.

getConfirmationCaption

protected java.lang.String getConfirmationCaption(SingleTableFormSheet stfs,
                                                  CatalogItem ci)

Get the caption for the default confirmation MsgForm.

Parameters:

stfs - the FormSheet that triggered the operation.

ci - the CatalogItem that is going to be removed.

getConfirmationText

protected java.lang.String getConfirmationText(SingleTableFormSheet stfs,
                                               CatalogItem ci)

Get the text for the default confirmation MsgForm.

Parameters:

stfs - the FormSheet that triggered the operation.

ci - the CatalogItem that is going to be removed.

getRemoveTransition

protected Transition getRemoveTransition(SingleTableFormSheet stfs)

Get the transition that performs the actual removal. This basically calls doRemove(org.salespointframework.core.SaleProcess, org.salespointframework.core.data.interfaces.CatalogItem, org.salespointframework.core.data.interfaces.DataBasket).

Parameters:

stfs - the FormSheet that triggered the operation.

doRemove

protected void doRemove(SaleProcess p,
                        CatalogItem ci,
                        DataBasket db)

Perform the actual removal.

Any error condition should be passed on to FormSheetStrategy.error(org.salespointframework.core.SaleProcess, int) in FormSheetStrategy.

Parameters:

p - the process in which this sub-process will be implanted.

ci - the CatalogItem to be removed. Can be null.

db - the DataBasket relative to which to perform the operation.
